In case you’re not familiar with the term, Gestalt is a whole that is more than the sum of its parts.
Marin named these bikes quite well. These are great bikes that give you more than the component list (or the prices) would suggest.
The Gestalt series aluminum frame is smooth and light (actually a bit lighter and springier than the steel Marin Nicasio or Fuji’s Sportive frame). It also comes with a fender and front-rack ready fork. The Gestalt versions that have mechanical (as opposed to hydraulic) brakes rely on the powerful Tekro Spyre models. All of these bikes feature internal cable runs and the fabulous 30mm Schwalbe G-One tires. In order to keep the prices reasonable, the Gestalt 1 comes with Shimano Sora components (for under $1100). The Gestalt 2 is equipped with a carbon fork and Sram GX-1 drivetrain for around $1200, and the Gestalt 3 goes with hydraulic disc brakes and Sram Rival parts for $2199.
